Vulnerability discussion

NIS/NIS+/yp files are part of the system's identification and authentication processes and are, therefore, critical to system security. ACLs on these files could result in unauthorized modification, which could compromise these processes and the system.

Check content

Determine if any NIS/NIS+/yp command files have an extended ACL. Check if extended permissions are disabled. Procedure: # aclget /var/nis # aclget /var/yp If extended permissions are not disabled, this is a finding.

Fix text

Remove the extended ACL from the NS/NIS+/yp command file(s) and disable extended permissions. #acledit < directory >/< file >

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
